reset activation timeout on manual deactivation

Previously, the wakeword trigger would only reset its activation
counter whenever it automatically deactivated the pipeline, due to
either a timeout or a vad deactivation. However, if the client manually
deactivated the pipeline, the counter's state would be retained for the
subsequent activation. This would shorten that activation's effective
timeout. These changes reset the activation counter whenever the
pipeline is inactive.
